Sway Bar Bushing Set - Front (21mm) by Powerflex Street

Sway Bar Bushing Set - Front (21mm) by Powerflex Street

Your car's suspension stabilizer bar, or swaybar, connects the suspension to the chassis and reduces body roll. If you turn your car sharply to the right, you'll feel the car (and you) lean to the left. The swaybar compensates for that momentum. The swaybar bushing is a piece of molded rubber or polyurethane that cushions the metal components of your suspension system and prevents them from rubbing against one another. If you feel vibration and/or hear excessive rubbing or squeaking when going over a pothole or bump, it might be time to replace your bushings. Performance poly bushings are often used for racing applications, or to lengthen the amount of life time between bushing replacement.

About Powerflex Street

Powerflex Street Logo® carries an extensive line of Powerflex Street Series performance polyurethane bushings designed specifically for street driven cars that may encounter rough roads, carbonated beverages, and children in the backseat. They are the compromise between a teeth shattering track car and a floaty bag of potato salad. Like all Powerflex bushings, Powerflex Street bushings come with a lifetime warranty.

There are two colors of bushings in the Street Series, each describing a durometer rating. The Red is the softest and is much more suited for engine mounts, especially where vibration dampening is required. Yellow scores about 70. This should be considered closest to a street bushing match, with the extra benefit of longevity and resistance to wear over rubber.

Beyond Yellow is the most popular Powerflex bushing color, Purple, which generally dials in around 80 on the Shore-A durometer scale. Some of these bushings that live in heavy duty, high wear situations, are also composed of large metal sections, reducing the amount of actual bushing material and further stiffening the overall attitude and strength of the bushing assembly.

Powerflex was formed as EPTG Ltd in the UK in 1996 to leverage recent advancements in polyurethane technology. The company developed a state of the art factory to create and manufacturer high performance automotive polyurethane components. The development of Powerflex remains completely in house, allowing for the strictest levels of quality control.
